Today is the seventy-first anniversary of the Japanese attack on Pearl Harbor, an act that brought us into World War II, pushed a reluctant America onto the world stage, and ushered in the age of empire. The official history of that event is that it was a "sneak attack" precipitated by war-crazed Japanese militarists, and that the totally unprepared Americans – kept from arming themselves by evil "isolationists" in Congress and the Republican party – were caught completely by surprise.

There is, however, one big problem with this official history: it’s a lie.

The truth is that, by the winter of 1941, the Americans had decrypted the various Japanese military and diplomatic codes: President Roosevelt, key members of his cabinet, and top military leaders, including Gen. George C. Marshall, US Army chief of staff, had access to this intelligence, which was intercepted, decoded, and transmitted directly to them. We know this because Robert Stinnett, in researching his seminal book, Day of Deceit: The Truth About FDR and Pearl Harbor, obtained heretofore unknown documents under the Freedom of Information Act, which trace the intelligence stream from interception stations throughout the Pacific to the 36 Americans cleared to look through what was, in effect, a window into Japanese plans and preparations for the Pearl Harbor attack. The President and 35 other Americans in top political and military circles knew where the attack was to take place, they knew when it was to take place, and they watched it unfold, step by step, with full knowledge of its import.
